Hibiscus plant &#39;Balhibred&#39;

ABSTRACT

A new and distinct cultivar of  Hibiscus moscheutos  plant named ‘Balhibred’, characterized by its upright and uniform plant habit, large, deep burgundy red-colored flowers, and light green-colored leaves.

LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED

Hibiscus moscheutos

VARIETY DENOMINATION

‘Balhibred’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hibiscus moscheutos, hereinafter referred to by the name ‘Balhibred’.

The new Hibiscus is a product of a planned breeding program conducted by the inventor in Elburn, Ill. The objective of the breeding program was to create new well-branched Hibiscus cultivars with desirable flower color, and uniform and compact plant habit appropriate for container production.

The new Hibiscus originated from a cross made by the inventor in Elburn, Ill. in 2000, of the Hibiscus mischeutos proprietary breeding line 114-7-2 (not patented), as the female, or seed, parent with the Hibiscus mischeutos proprietary breeding line 116-23-5 (not patented), as the male, or pollen, parent. The female parent, Hibiscus moscheutos proprietary breeding line 114-7-2, is fairly tall with a good habit and deep red flowers. The male parent, Hibiscus mischeutos proprietary breeding line 116-23-5 has medium height with a good habit and medium pink flowers and good fertility.

Compared to plants of the female parent, Hibiscus mischeutos proprietary breeding line 114-7-2, the cultivar ‘Balhibred’ is more compact, better branched, and more free flowering than the female parent.

Compared to plants of male parent, Hibiscus mischeutos proprietary breeding line 116-23-5, the flowers of the cultivar ‘Balhibred’ are deep burgundy red whereas the flowers of the male parent are medium pink. The cultivar ‘Balhibred’ is more vigorous and more free flowering, and has larger flowers than the male parent.

The cultivar ‘Balhibred’ was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Elburn, Ill., on Aug. 7, 2001. The cultivar ‘Balhibred’ is perennial to Zone 5.

Both parents have a degree of homozygosity such that the progeny of the cross 114-7-2 times 116-23-5 are phenotypically uniform and essentially identical to ‘Balhibred’. Removal of the terminal apex will improve branching in asexually reproduced plants. Accordingly, plants that are phenotypically identical to ‘Balhibred’ can be produced by sexual reproduction as well as asexual reproduction.

Asexual reproduction of the new Hibiscus by vegetative terminal cuttings taken in a controlled environment in Santa Paula, Calif. has shown that the unique features of this new Hibiscus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Balhibred’. These characteristics in combination distinguish ‘Balhibred’ as a new and distinct cultivar:

1. Compact, upright, and symmetrical plant habit that is suitable for container production;

2. Early to flower;

3. Bushy, well branched;

4. Large flowered and floriferous; and

5. Deep burgundy red flowers.

Plants of the new Hibiscus ‘Bahlibred’ can be compared to plants of the Hibiscus Disco Belle Series Pink (not patented), commercially available from Sakata Seed, Inc., Morgan Hill, Calif. 95037. In side-by-side comparisons conducted in Santa Paula, Calif., plants of the new Hibiscus ‘Balhibred’ differ from plants of Disco Belle Series Pink in the following characteristics:

1. Plants of the new Hibiscus ‘Balhibred’ are 20% more compact;

2. Plants of the new Hibiscus ‘Balhibred’ are earlier to flower by approximately one week;

3. Plants of the new Hibiscus ‘Balhibred’ have more branches;

4. Plants of the new Hibiscus ‘Balhibred’ are branched more uniformly; and

5. Plants of the new Hibiscus ‘Balhibred’ are more floriferous.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph differ from the color values cited in the detailed botanical description that accurately describe the colors of the new Hibiscus. The photograph comprises a side perspective view of a single flowering plant of ‘Balhibred’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The cultivar ‘Balhibred’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, light intensity, water status and/or fertilizer rate or type without, however, any variance in genotype.

The photographs and following observations, measurements and values describe plants grown in Santa Paula, Calif. with 1 plant per 15 cm container in glass-covered greenhouses during the winter and spring under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 18 to 23° C. and night temperatures ranged from 16 and 21° C. Plants and controls were treated with plant growth regulators as follows: one time with Cycocel at 250 ppm, followed by two times with a mixture of B-9 at 2500 ppm and Cycocel at 500 ppm. Plants were approximately 6 months old when the photographs and color values were determined. The chart used in the identification of the colors described herein is the R.H.S. Colour Chart of The Royal Horticultural Society, London, England. The color values were determined on Jun. 23, 2003 between 10:00 am and 2:00 pm under natural daylight conditions.
